MACHINE FOR PRINTING YARNS.

SPECIFICATION forming part of Letters Patent No. 471,561, dated March 29, 1892.

Application filed January 26, 1891- Serial No. 379,079. (No model.)

To all whom it may concern.-

Be it known that we, GIULIO MARGHETTI, residing at Halifax, England, and HERBERT CROssLEY, residing at London, England, subjects of the Queen of Great Britain, have intermed spaced colors, suitable for being used more particularly in the manufacture of tapestry and tapestry-velvet carpets, rugs, and similar fabrics.

In the machinery at present employed for printing yarns for use in the manufacture of the above-named fabrics the yarn to be printed is wound upon a drum, and the printing is usually effected by means of traveling color-boxes, each carrying a disk, or what is termed in the trade a pulley, the said pulleys revolving in the coloring-matter contained in the traveling color-boxes and printing upon the yarn as the traveling color-boxes pass from side to side of the drum. It has also been proposed to employ sticks or rulers covered with felt and supplied with color from a sieve and applied horizontally across the breadth of the drum.

According to our invention, instead of using traveling color-boxes carrying disks or pulleys traveling under the drum, we make use of what we term color or printing bars and fcolor-troughs.

Our color or printing bars and color-troughs are situated under the drum and the colorbars are adapted during the operation of printing to have an up-and-downmovement communicated to them, while the colortroughs remain stationary, so that they may slip into the troughs. The color or printing bars are raised and lowered by any suitable mechanical contrivance, and springs can witlr advantage be used to regulate the pressure of printing portion or portions of the said colorbar is or are pressed against the yarn on the drum, and one scroll or line is thereby. printed across the yarn on the drum. The .said color-bar is then returned to the colortrongh, and if another scroll or line of the scribed, moved out of the Way and another color-bar and color-trough substituted, the color-trough containing coloring-matter of the required shade, and the operation; is repeated as above described.

The faces of the color-bars may withadvantage be grooved or fluted or concave, and

they may be in some cases provided with fixed or movable sides projecting above the faces of the color-bars.

In some cases we find it advantageous to form the periphery of the drum of iron or other suitable metal instead of the wooden lags hitherto usually employed, the metal periphery being covered, if found necessary,with india-rubber, felt, or other analogous material.

In order to enable our invention to be fully understood we will describe howit can be carried into practice by reference to the accompanying drawings, in which- .Figures 1 and 2 are respectively views of opposite sides of a machine for printing yarns constructed with our improvements. Fig. 3 is a front elevation of the same. Figs. 4 and 5 are respectively a plan and elevation of a detail drawn to an enlarged scale. Fig. 6 is a side view of our color or printing bar, and

Similar reference-letters indicate similar or corresponding parts throughout the drawings. a a a represent our color or printing bars a number of which, as shown in Figs. 1, 2, and

3, are placed under the drum 1) of the machine, and which drum may be of ordinary construction, but which we prefer to construct as hereinafter described.

0 c 0 represent the color-troughs of the color-bars. These color-troughs c are mounted on a sliding table 0', supported and working on slides 0 attached at their extremities to cross-rails A, secured to the frame A of the machine. To the sliding table 0 is secured a bracket 0 provided with a female screwthread designed to engage with the male screwthread of a screw (1, the said screw being supported and having its bearings in brackets d, secured to therails A. By turning the screw d the table 0 is caused to move along the slides 0 so as to bring each color-trough with its color or printing bar into posit-ion for printing. Motion is given to the said screw by means of a series of bevel-wheels e, which are actuated by a handle e. We advantageously provide a recessed stop e for thereception of the handle e, so as to serve as an indicator to show when one of the colortroughs with its color or printing bar is in the position for printing, the movement of each consecutive trough and bar into such position v being effected by one revolution of the said handle.

Our color or printing bars a are shaped, as shown, so that when at rest theircentral portions extend or pass into the troughs c, and their ends are supported in recesses forming guides c at the ends of the said troughs. The

ends of the bars project through the said recesses, so as to allow the bars to be lifted up, as hereinafter described, to print the yarn on the drum 1).

In order to operate each color-bar for the purpose of printing the yarn, we provide compound slidesf, which are located beneath the center of the drum 1) and serve (when each color-trough is moved, as hereinbefore described, soas to bring the ends of its colorbar over the said slides) to lift the said bar from the'trough and into contact with the yarn on the drum 1). Each of the compound slides f, as shown clearly in Figs. 4 and 5, consists of two slides f and f the slide f sliding in a supporting-bracket f secured to the frame A, and the slide f sliding in the slide f.

'f are springs for regulating the pressure of the color-bars when moved against the yarn by the compound slides, they being located in recessesin the slides f f The said springs serve to support the slides f in the slides f and are therefore more or less compressed when the color-bars are brought into contact with the yarn, according to the degree of movement imparted to the said bars fat the side of the drum b, from which the yarn is stripped, can be lifted from its place when such stripping occurs. The movement of the compound slides f is effected by means of a cam g through the medium of levers g, shaft 9 lever 9 rod g and lever 95, the latter being provided with a roller g, which bears on the cam g. The said cam rotates ona shaft h, fixed in brackets h on extensions B on the frame A, and is operated from the driving-pulley '5 through the medium of a spur-wheel i, pinion i and shaft i the cam g, together with a cam j, be ing attached to the wheel i. The said camj serves to rotate the, drum bin the usual manner. The pinion 11 forms part of a clutch and is loose on the shaft i the other part i of the clutch being arranged to slide on a spline on the said shaft 2' serves to connect the mechanism for rotating The clutch 71 the drum 1) and for lifting the color or printing bars a with the driving-pulleyvl and is thrown in and out of gear by any well-known means, such as by means of a lever. I

The operation of printing yarn by the mechanism hereinbefore described is as follows-that is to say: Assuming that the drum 1) has been covered in the usual manner with the yarn to be printed and the color-troughs 0, containing the necessary colors, and our color or printing bars a be arranged in any required order on the table 0, if the said table be moved by its handle e so as to bring one of the color-troughs and its bar centrally above the compound slides f and the cam g be revolved in the direction of the arrow, Fig. 3, the said compound slides will be raised, and during their upward movement their re oesses f will embrace the said color-bar and carry it with them intheirupwa'rd movement untilthe face of the bar is brought into contact with the yarn on the drum b, so as to print a line or scroll on the yarn, the upward movement of the slide f of he said compound slide being continued until the necessary amount of pressure is brought to bear upon the color ,or printing bar by the compression of the springsft It will be obvious that the strength of the springsf can be varied in order to suit various kinds of yarns. After printing such line or scroll the compound slide is lowered, vcarrying with it the color-bar, which during the downward movement is returned to the color-trough and again immersed in the color, the downward movement ofthe slidesfcontinuing until the recesses f are disengaged from the ends of the color-bar. The drum b must then be rotated by the camj, in the usual well-known manner, for the yarn to be brought intoposition toreceive another line or scroll, and should itbe desired to print another line or scroll of the same color as that of the last line or scroll the cam Q will cause a repetition ofthe movements above described to take place. Should it, however, be desired to print a line or scroll of a different color, the sliding table 0 must be operated by its handle 6, so

I'IO

' willbe effected in a similar manner to that above described.

Our color-bars can, as shown in Figs. to 14, be grooved or fluted on the face or printing-surface, and, in order to increase the stability of the said bars, we sometimes, as shown in Figs. 7 and 12, provide each of them with a tie-rod a. the ends of which pass through lugs a? on the bar, so that it can be put in tension by means of nuts a In some cases we provide each of the said bars with movable sides (L as shown in Figs. 8 and 13, which sides project above the face or printing-surface ofthe bar and form a trough for the color, and are kept in such position by means of a spring a attached to the bar by screws, as shown, so that when the bar is brought into contact with the yarn the sides a are caused to yield, and the face of the bar is brought against the said yarn. In Fig. 10 the sides of the bar are shown fixed or inte gral with the bar. We sometimes also form the face or printing-surface of each bar on a separate strip or block d of india-rubber or other suitable material, as shown in Figs. 9

and 14, the said strip or block being held in a groove a in the bar. In Figs. 15, 16,17, and 18 the color bars are shown with concave printing-surfaces.

\Ve will now describe, by reference to Figs. 1, 2, and 3, the drum, which we find it advantageous to employ in combination with our color bars and troughs. b is the periphery of the said drum 5, which periphery we find may be most advantageously made of iron, and is connected by meansof arms I) to bosses b keyed on a hollow shaft 19 The periphery b is covered with acovering of flexible materialsnch as india-rubberattached to the said periphery and to the leaves, hereinafter described, of the drum.

k are rings secured to the bosses b by means of arms in, each ring being formed in two pieces, which are held together by bolts and nuts 10 and clip the arms 12 and Upon each ring is are two projections 10 to which are secured stays Z, which serve to stay the fixed portions of the periphery b together through the medium of brackets Z and studs Z In order to facilitate the stripping of the drumthat is to say, the removal of the printed yarn from the sameit is provided with two pairs of leaves m, which are hinged on the studs Z The said leaves are held in their closed position, as shown by the full lines in Fig. 1, by links at and 0, which are secured by means of studs 19 to extensions 19 10 on a segmental spur-wheel g, which wheel can turn freely upon the shaft 17 it being held in place by the bosses b 7" is a spur-pinion which gears with the teeth of the wheel q, the said pinion being keyed on a shaft r, supported by brackets secured to the rings is and having a hand-wheel r keyed thereon, the said wheel serving, by means of the pinion r, to rotate the wheel q and move theleavesminto the position shown by the dotted lines in Fig. 1, so as to enable the drum 1) to be stripped. Through a screwthreaded hole in one of the rings 70 works a screw 8, to one end of which is secured a handwheel 3', the said screw when the leaves of the drum 1? are closed preparatory to printing being screwed up, so that its other end enters a hole in the projection 10 of the segmental wheel q, thus securing the said wheel and keeping the leaves closed. When it is desired toopen the leavesm, as hereinbefore described, the screw 8 must be withdrawn from the hole in the wheel q, as will be obvious. Thelinks n are each constructed in two pieces to facilitate their adjustment to the required length by means of bolts and nuts n and slots 02 The links it are provided toward one extremity with slots n", which slots enable the links at to slide freely upon the pins 19 during the movement of the segmental wheel q, andby this means prevent the leaves from being forced beyond the normal circu mferen tial line of the drum when the links 'n come into the radial line. In the slots a are also secured studs n by means of nuts n rollers n being arranged on the said studs, so as to roll against the links 0 as the leaves m are being opened, in order to prevent the leaves of each pair from coming in contact.

The drum 1) is filled in the well'know n inanner by the usual mechanism carried by the brackets 15 and t, and we find it advantageous, as hitherto, to windasheet of oil-cloth round the said drum before filling withyarn.

The frame A on one side of the drum is provided with the hinged portion A which can be let down in the usual manner when too stripping the drum, and upon the said hinged ing' provided with a hinged cap a, secured by means of a screw v. provided with a handwheel M1 The shaft 6 is also supported by a pedestal 21, mounted on the frame A at the side of the drum opposite to the hinged portion A and in order to facilitate the opening of the said hinged portion the said pedestal o is hinged to its base, as shown at n, Fig. 3. When itis necessary to strip the drum 1), the pedestal-cap u is released by means of the screw a and the pedestal '0, acting as a fulcrum for the shaft b the end of the shaft farthest from the drum is depressed by an eyebolt o thereby allowing the hinged portion cured to the cross-rail 13 on the extensions B.

Having now particularly described and as certained the nature of our said invention and in what manner the same is to be performed, We declare that what we claim is- 1. In machinery for printing yarns in spaced colors, color or printing bars, in combination with color-troughs, and means for bringing each color-bar and its trough into the required position under the drum of the machine, and for communicating a vertical upward movement to the said color-bar for printing the line or scroll and for returning the bar to its trough, substantially as described.

2. In yarn-printing machinery, the combination, with the drum, of color-troughs and color-bars, means for shifting the colortroughs to bring the desired color-bar beneath the drum, and the slidesf, all substantially as set forth.

3. The combination, with color-bars such as those herein described, 01": color-troughs having recesses at their ends to receive the ends of said bars, means for shifting the color-troughs to bring the desired color-bars beneath the drum, and means for raising and lowering said bars, substantially as described.

4. In machinery for printing yarns, the combination, with the drum and with the color bars and troughs, of the mechanism, substantially as described, for operating said bars and troughs, consisting of devices serving to shiftthe trough with the desired bar directly beneath the drum and to raise the bar as needed into contact with theyarn on;

the color bars and troughs constructed and operating as set forth, compound slides ff, the drum provided with hinged leavesand links, as described, and the frame having thehinged portion A all substantially as set forth.
